PLAITING-MAOHINE.

Specioation of Letters Patent.

Patented Mar. 15, 1921.

Be it known that l, JAMES W. BRUNPAGE, a citizen of the United States, and resident of Akron, Ohio, have invented certain new and useful Improvements in Plaiting-Machilies, of which the following 1s a specilic-ation.

My present invention relates to an im-v proved plaiting machine or apparatus and is designed for the purpose or ornamenting various articles madel of thin rubber by plaiting'or gathering, puckering or corru gating the material and at the same time attaching tothe material a band of rubber in a simple and expeditious manner.

The machine is particularly designed to accomplish this work around the limb and waist openings of rubberl diaper c overs but obviously it may be used for s1m1la r ornamentation of other articles of wearing apparel.

The invention comprises the novel com.- bination of elements and also the arrangement of parts as hereinafter described, the nature and scope of my invention belng defined by the claims appended hereto.

An embodiment of my invention .is illustrated in the accompanying drawings 1n which,-

Figure 1 is a plan view of a machine 4or apparatus such as referred to.

Fig. 2 is a side elevation, and

Fig. 3 is an end elevation.

Referring more particularly to these drawings the essential parts of the apparatus comprise a corrugated roller or cylinder 7 having corrugations entirely across its face, and a second roller or cylinder formed of two corrugated portions 8, having corrugations which coact with cylinder 7, but the sum of whose faces is less than the face of the cylinder 7, and having a plain cylindrical portion located between them'. The plain portion 11 is of such a diameter that when the corrugated portions 7 and 8 are in proper mesh or engagement the surface of portion 11 will closely approach the top of the corrugations of 7. If a band of uncured rubber compound similar to dental dam rubber and wider than the face of portion l1 be fed through betweenl the described rollers or cylinders, it will be liuted or gathered in accordance with the shape of the corrugations andlif at the same time, a second strip of the same or similar material plaits or folds in the material operated on but it will be understood that by the term corrugated I include any form of intaglio and relief which will produce a puckered or wrinkled and hence ornamental surface, the design being capable of being changed to suit individual tastes without departing from the spirit of my invention.

In operating upon such articles as diaper covers, in the manufacture of which it is desirable to place such ornamentation around the edge of openings, it is necessary to prov1de means for separating the two cylinders so as to admit and remove the garment. To

accomplish this in the form shown, l have 'mounted the cylinder 7 upon a shaft l2 disposed in rigid bearin in the main frame 1 and have mounted t e cylinder 8 upon a shaft 14, parallel to shaft 12 and journaled in bearings in a swing frame 21 pivoted on a horizontal shaft 15 journaled in bearings in the posts 1*l of the main frame of the machine. 'A spring 9 serves tonormally separate the two cylinders so that the material acted upon may be inserted or removed and a foot treadle 2 connected by rod 2a to the swing frame is used to exert the necessary pressure to bring the rolls together. An adjustable stop 3 limits the pressure which may be applied. 1

l have also provided a pair of ordinary spur gears 4 and 5 on shafts 12 and 14, which meshtogether drive the shafts at the same speed; these gears vprevent the material from being subjected to the driving strain and being crushed thereby or ruptured.

The shaft 14, also'carries a worm gear 22 by means of which the shaft is driven. A worm 23 is mounted in position to mesh with the worm gear 22 and is in turn driven by a motor through clutch 24. An auxiliary roller 18 is mounted on a swing frame 17,

which is pivoted on swing frame 25, the lroller being supported directl tionl 11 and in contact therewit which contact is maintained by the weight of roller 18 and swing frame. In practice the narrow strip of rubber is fed between portion 11 and roller 18 before traveling around the ortion 11 and entering between disks 11 an 7 ,the purpose of roller 18 being to insure uniform feeding of the strip without excessive tension. Having thus described my invention what I claim is:

1. Apparatus of the character described comprising a roller having a peripheral s urface provided with corrugations extending the entire lenv h thereof, a second roller'of substantially t e same length coacting therewith and having a portion of its surface correspondingly corrugated and another portion of p ain cylindrical formation and arran ed to coact with the corrugations on said tgirst roller, and means for rotating said rollers in unison.

2. Apparatus of the character, described comprising a roller having a corrugated peripheral surface throughout its entire length, a second roller arranged to coact therewith and having side portions provided with corresponding corrugations, and an intermediate plain cylindrical portion arran ed to coact with the intermediate corrugate portion of said first named roller, and means for rotating said rollers.

3. Apparatus of the character described comprising a roller having longitudinal corrugations throughout its entire-periphery, a

second roller arranged to coact therewith and having a portion of its surface 'prof l' above por;A

vided with coacting corru ations and another portion of plain cyliny rical formation with t e eriphery thereof at substantially -the same istance from the axis of the roller as the periphery of the corrugations.

4. Apparatus ofthe character described comprising a roller having a corrugated peripheral surface, a second roller arranged to coact therewith and having a portion of its peripheral surface corru ated and an ad- `jacent portion if plain cy indrical formation, one ofsai'd rollers being mounted on a swinging axis, and means for rotating said comprising a roller journaled on a station-p ary axis and having a corrugated peripheral surface, a second roller` journaled on an axis which is movable toward and from the first named roller and having a ortion of its peripheral surface corrugate and an ad'- Joining portion of plain cylindrical formation, and a presser roller mounted on an axis which is movable toward and from the axis of said second roller and having a plain peripheral surface normally contacting with the plain cylindrical portion of the surface of said second roller. p

' In testimony whereof I aiix my signature.

JAMES WILLIAM BRUNDAGE.
